S82YVM30D
A momentary power failure has occurred in the
input.
A momentary overload has occurred.
A momentary output voltage drop has occurred
at startup due to the capacity of the capacitive
factors on the load side or when the load is acti-
vated.
The output voltage has returned to normal volt-
age following a rapid drop caused by using the
output voltage adjuster (V.ADJ).
Deterioration due to age (when the Power Sup-
ply has been used for several years)
Overload (immediately following first use of the
Power Supply or when increasing the load)
The output voltage dropped to -10% or lower of
the rated voltage resulting from using the output
voltage adjuster (V.ADJ)
A sudden overload occurred and the Power
Supply remains in overload status.
The output voltage remains low after a rapid
voltage drop caused by using the output voltage
adjuster (V.ADJ).
The overload status continues to fluctuate fol-
lowing a sudden overload.
Deterioration due to age (after using the Power
Supply for several years)
Overload (immediately following first use of the
Power Supply or when increasing the load)
Power Supply interrupted or damaged.
Overvoltage protection operation
The short bar has fallen off, or the +S and -S ter-
minals are open.
Output short-circuit
Intermittent operation due to overload (S8VM-
01524A@/03024A@ only)
The Power Supply fails to start repeatedly due
to the capacity of the capacitive factors on the
load side.
The input turns ON and OFF repeatedly.
The status repeatedly switches between normal
operation and output short-circuit.
Probable cause of error
---
Check that the output voltage is normal and no problems have occurred in other devices. No problems
will be caused by continuing to use the Power Supply as is. To clear DC LOW1 (LED display and tran-
sistor output status), turn OFF the input power, and wait at least 60 s before turning ON the input Power
Supply again.
The load current has probably exceeded the rated current. We suggest reducing the connected load
or replace the Power Supply with one that has a higher capacity.
A large inrush current has probably flowed to the load side at startup. We suggest replacing the Power
Supply with one that has a higher capacity.
Turn OFF the input power, and wait at least 60 s before turning ON the input power again to clear the
indicator status.
The internal parts of the Power Supply may have deteriorated due to age. We suggest replacing the
Power Supply. Also replace other Power Supplies that were purchased at the same time.
The load current has probably exceeded the rated current. Check the actual load current and Power
Supply capacity. Continued use in overload status may damage the Power Supply.
Adjust the output voltage to the rated values using the output voltage adjuster (V.ADJ).
An error has probably occurred in the load device. Turn OFF the input power, and check whether any
errors have occurred in the load device. Continued use in overload status may damage the Power Sup-
ply.
Adjust the output voltage to the rated values using the output voltage adjuster (V.ADJ). To clear DC
LOW1 (LED display and transistor output status), turn OFF the input power, and wait at least 60 s be-
fore turning ON the input power again.
An error has probably occurred in the load device. Turn OFF the input power, and check whether any
errors have occurred in the load device. Continued use in overload status may damage the Power Sup-
ply.
The internal parts of the Power Supply may have deteriorated due to age. Replace the Power Supply.
Also replace other Power Supplies that were purchased at the same time.
The load current has probably exceeded the rated current. Check the actual load current and Power
Supply capacity. Continued use in overload status may damage the Power Supply.
Check whether the input power is being applied correctly. If there is no output even though the input
power is applied correctly, the internal circuit is probably damaged.
Turn OFF the input power, and wait at least 3 min before turning ON the input power again. If the same
status recurs, the internal circuit is probably damaged.
Check whether the +S and -S terminals are open. If so, the overvoltage protection function is activated.
Therefore, turn OFF the input power and wait at least three minutes before turning it ON again. (S8VM-
10024A@/P@ and S8VM-15024A@/P@ models only)
Remove the cause of the output short-circuit.
The load current has probably exceeded the rated current. Check the actual load current and Power
Supply capacity. Continued use in overload status may damage the Power Supply.
A large inrush current has probably flowed to the load side at startup. We suggest replacing the Power
Supply with one that has a higher capacity.
Check whether the Power Supply’s input voltage is being applied correctly.
An error has probably occurred in the load device. Turn OFF the input power, and check whether any
errors have occurred in the load device.
